I have a problem to change my date of birth, your site tells me "You Need a Parent's Permission"
I am offered to update my account with the link "https://my.minecraft.net " but it does not work
I specify that I am of age
If you need to change your date of birth, please contact us here https://help.minecraft.net/hc/en-us/requests/new … and provide your Transaction ID from date of purchase. We will need to verify your Transaction ID in order to make this update. I hope this helps! ^SA
